Key Solutions / Use Cases
Server Consolidation and Containment – Eliminate server sprawl
by deploying systems into virtual machines
Infrastructure Provisioning – Reduce the time for provisioning new
infrastructure to minutes with sophisticated automation
capabilities.
Business Continuity – Reduce the cost and complexity of
business continuity by encapsulating entire systems files that can
be replicated and restored onto any target server
Test and Development – Rapidly provision and re-provision test
and development servers; store libraries of pre-configured test
machines
Enterprise Desktop – Secure unmanaged PCs. Alternatively,
provide standardized enterprise desktop environments hosted on
servers.
Legacy Application Re-hosting – Migrate legacy operating
systems and software applications to virtual machines running on
new hardware for better reliability

needed)
• Safeguard for using memory overcommit feature
with confidence
• Reclaim Performance
Beta Feedback
“Great for memory over-subscription.”
Physical Memory (Physical Host)
Proof Point
1,000x faster
than swap-in!

Who gets what share
of the vmnic?
•
Traffic typically converged to two 10 GigE
NICs
•
Some traffic types & flows could dominate
others through oversubscription

Preconfigured
Traffic Classes
e.g. VM traffic in this example:
- limited to max of 500 Mbps (aggregate of all VMs)
- with minimum of 50/400 of pNIC bandwidth (50/(100+100+50+50+50+50)
Guaranteed minimum
service level
NIC Teaming Enhancements—Load Based Teaming (LBT)
Distributed Virtual Port Group configuration panel
Note: adjacent physical switch
configuration is same as other
teaming types (except IP-hash).
i.e. same L2 domain
Load Based Teaming (LBT) – only available with vDS
• Existing vSphere 4.0 teaming modes use static virtual port to pNIC allocation—teaming algorithms do not account for load
• LBT Goal: avoid congestion by balancing load on the team
• LBT invoked if saturation detected on Tx or Rx (>75% mean utilization over 30s period)
• 30 sec period—long period avoids mac address flapping issues with adjacent physical switches
• Note: Current implementation does not take NetIORM shares into account
vSphere 4.1—Network Feature Summary
Network Performance & Scale Improvements
• vmkernel TCP/IP stack—vMotion, NFS, FT logging performance gains
• UDP and intra-host VM to VM performance improvements
• vDS scaling to ~350 hosts/vDS (from current 64 hosts/vDS)—final number is TBD!
Traffic Management (*vDS only* features)
• NetIOC (Network I/O Control)
 Software scheduler to guarantee service levels for specified traffic types
• LBT (Load Based Teaming)
 Avoid congestion by dynamic adjustment to NIC team based upon pNIC load
IPv6—NIST Compliance
• Compliance with NIST “Host” Profile
Nexus 1000V Enhancements
• Additional Nexus 1000V features—Nexus 1000V V1.4 or 2.0

The I/O Sharing Problem
• Low priority VM can limit I/O bandwidth for high priority VMs
• Storage I/O allocation should be in line with VM priorities

Set granular policies
that define only certain
virtual machine
movements
• A cloud enabler(multi-tenancy)

DRS Host Affinity
Required rules
Preferential rules
Rule enforcement: 2 options
• Required: DRS/HA will never violate the rule;
event generated if violated manually. Only advised
for enforcing host-based licensing of ISV apps.
• Preferential: DRS/HA will violate the rule if
necessary for failover or for maintaining
availability
DPM Enhancements
Scheduling Distributed Power Management
• Turning on/off DPM is now a scheduled task
• DPM can be turned off prior to business hours in anticipation for higher resource
demands
Disabling DPM brings hosts out of standby
• Eliminates risk of ESX hosts being stuck in standby mode while DPM is disabled.
• Ensures that when DPM is disabled, all hosts are powered on and ready to
accommodate load increases.
vMotion Enhancements
• Significantly decreased the overall migration time (time will vary depending on
workload)
• Increased number of concurrent vMotions:
 ESX host:
- 4 on a 1 Gbps network and
- 8 on a 10 Gbps network
 Datastore: 128 (both VMFS and NFS)
• Elapsed time reduced by 5x on 10GbE tests
• Maintenance mode evacuation time is greatly decreased due to above
improvements
Fault Tolerance (FT) Enhancements
FT fully integrated with DRS
DRS
• DRS load balances FT Primary and
Secondary VMs. EVC required.
FT Primary
VM
FT Secondary
VM
Versioning control lifts
requirement on ESX build
consistency
• Primary VM can run on host with a
Resource Pool
different build # as Secondary VM.
Events for Primary VM vs.
Secondary VM differentiated
• Events logged/stored differently.
HA Diagnostic and Reliability Improvements
HA Healthcheck Status
• HA provides an ongoing healthcheck facility to ensure that the required cluster
configuration is met at all times. Deviations result in an event or alarm on the
cluster.
HA Operational Status
• A new Cluster Operational Status
window displays more information
about the current HA operational
status, including the specific status
and errors for each host in the
HA cluster.
Improved HA-DRS interoperability during HA failover
• DRS will perform vMotion to free up contiguous resources (i.e. on one host) so
that HA can place a VM that needs to be restarted
HA app awareness – expose APIs for 3rd party app developers
